feat(04-01): refactor all notify() call sites to use structured NotificationOptions

- Change ipc-support.ts notify() from (title, body) to (options: NotificationOptions)
- Wire createNotificationService in bootstrap-application.ts with lazy service graph refs
- Update all 12 call sites with entity context, urgency, navigation, and batch keys
- Update dependency interfaces in service-graph, worker, orchestration, automation, updater, desktop-shell
- No string-based notify() calls remain in src/main/
